Description

The invention relates to pneumatic conveying, in particular to devices for conveying highly concentrated suspensions, namely to remove semi-dry filter cake from sugar mills at high concentrations (up to 55-57% solids).

The purpose of the invention is to increase the removal efficiency of an aeromaterial mixture.

This goal is achieved by the fact that in the device containing the housing, in the upper part of which the outlet end of the pump screw casing is integrated and a nozzle for supplying compressed air and a nozzle for discharging the aeromaterial mixture located in the same vertical plane mounted one against the other are integrated in the lower part of the housing with the location of the lower wall of the first pipe above the lower wall of the second according to the invention between the pipe for supplying compressed air and the pipe for the removal of the aeromaterial mixture ene group arranged one below the other plate, the upper part of which is disposed horizontally, and the bottom - with a slope toward the bottom wall of the nozzle for discharging azromaterialnoy mixture

The drawing shows a camera, General view.

The chamber consists of a screw pump 1 with a receiving hopper 2, a connecting pipe 3, an aeration chamber 4, in which are placed mainly horizontally and with a slight slope in the direction of movement of the material of the plate 5. of the common frame b, on which the screw pump 1 is mounted and to which the pipe is attached supply of compressed air 7 to the aeration chamber 4,

A material pipe 8 and a compressed air pipe 7 are connected to opposite ends of the chamber. The chamber is conventionally divided into three sections:

section A - overclocking;

section B - stabilization;

section B - final flow formation.

The camera operates as follows. A filter cake with a solids content of 55-57% is fed to a receiving hopper storage 2, from where

screw pump 1 moves into the connecting pipe 3 and then enters the aeration chamber 4 on horizontal or installed with a slight slope in the direction of movement of the material of the plate 5.

Compressed air is supplied through line 7 to the acceleration section A of the aeration chamber 4, where due to the presence of plates 5 it uniformly fills the cross section of the aeration chamber, preserving npf

the energy of the jet. The same plastics 5 serve both for a uniform distribution and in cross section of the aeration chamber of the transported material coming into it from the screw pump. Location on

the final formation of stream B, the transported mater is transported to the destination. The use of plates in the aerial camera ensures the formation of a uniform dense layer of cycran3w and

Claims (1)

full use of the kinetic energy of compressed air, which carries out the movement of the suspension through the material pipeline. SUMMARY OF THE INVENTION An aeration chamber to a screw pump, comprising a housing, in the upper part of which an output end of the pump screw housing is integrated, and a nozzle for supplying compressed air and a nozzle for discharging the aeromaterial mixture located in the same vertical plane mounted one against the other are integrated in the lower part housing with the location of the lower wall of the first pipe above the lower wall of the second, characterized in that that, in order to increase efficiency, a group of plates located one below the other is installed between the nozzle for supplying compressed air and the nozzle for removing the aeromaterial mixture, the upper part of which is located horizontally, and the lower one with an inclination towards the lower wall of the nozzle for the removal of the aeromaterial mixture.
